I stayed at this place for two days in February 2016.
Advantages: clean, great location (5min to bts, street with massages, food and all you could possibly need - 30 sec walk distance, but the neighborhood is really calm). The building is easy to find. All problems was solved instantly (I forgot combination to safe, problems with electricity). Really great support!
Michelle was really nice and easygoing.
The only disadvantage was that there is no elevator, so we carried our really heavy luggage to the 4th floor, which I cannot count as a nice experience. But to be honest, one of the pieces was carried by a guy who was working for Michelle, but we carried the rest.
Tips for those who will decide to stay at this apartment: there is the best Thai massage place just 5 min from this apartment. I don't remember exact name but it is something like centre of nontraditional medicine supported (or established) by princess. I have been at at least 5 cities and have done at least 20 massage during my stay in Thai, but this place was absolutely number one in my personal raining.
The famous (and fabulous) sky bar is 10 min from the apartment. Cocktails are really expensive, I was charged about 30 dollars for margarita, but you can just go there, enjoy the most amazing toproof view and go back home without ordering anything.
